DEMI LOVATO IS 'BACK' | Sends Video Message to Fans

"I wanted to let you guys know that I am back," says Demi Lovato in a new viral message to her fans. "I wouldn't be here today if it wasn't for your support."
This is the Disney star's first video since leaving a treatment center in Chicago. Lovato checked herself into rehab back in October 2010 to treat "physical and emotional issues."
